Answer: The required solution is x = 21.

Step-by-step explanation: We are given to solve the following equation for x :

"Square root of x minus 5 + 7 = 11."

The given equation can be written and solved as follows :


√(x-5)+7=11\\\\\Rightarrow √(x-5)=11-7\\\\\Rightarrow √(x-5)=4\\\\\Rightarrow x-5=4^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{Squaring both sides}]\\\\\Rightarrow x-5=16\\\\\Rightarrow x=16+5\\\\\Rightarrow x=21.

Thus, the required solution is x = 21.
